Contributed to the source-academy/frontend repository by developing enhanced data visualizers and tree rendering features, focusing on clearer insights from tree-structured data. Built new binary and general tree visualizers using React and TypeScript, improving both the user interface and rendering reliability. Refactored core components for maintainability through object-oriented design, addressed input validation, and resolved issues with rendering stability and tree verification. Improved UI aesthetics and user interactions, including formatting and checkbox behavior. Collaborated closely with other contributors, ensuring code quality through lint cleanups and removal of unused code, and established a foundation for future enhancements in data visualization and maintainability.
